FUEL FEEDER FOR GAS GENEEATORS.

Application inea october z, 1920. serial No. 414,315.

To all whom t may concern:

Be it known that we, JOHN E. SHARP and ALVIN J. BAssE'rr, both citizens of the United States, and residents of Milwaukee, in the county of Milwaukee and State of `Wisconsin, have invented certain new and useful Improvements' in Fuel Feeders for Gas Generators; and we do hereby declare that the following is a full, clear, and exact description thereof.

Our invention relates to gas producing apparatus and particularly to fuel feeding mechanism for a gas producing` generator.

1t is the object to provide improved mech-v anism for feeding fuel to a grate and for cleaning the grate of the remains of burnt fuel, and to this end we provide means whereby the fuel feeding mechanism and the grate clearing mechanism may be operated in unison or separately, as desired, or as occasion may demand, and whereby a predetermined amount of fuel is delivered to the grate intermittently at evenly spaced intervals.

Our invention is susceptible of embodiI ment in a variety of mechanical structures, one of which is illustrated inthe accompanying drawings, but it is to be understood that the structure shown is merely intended to disclose the essential features of our invention and that its scope is as de trol means.

Referring to the drawings in detail, 10 designates generally a generator structure of any well known or preferred design, equipped with rotary grate bars 11, only one of which is shown, and having an opening 12 in its upper wall for the passage of the fuel to be fed to said grate. l

The grate bars 11 include terminal -shaft extensions 13 and let mounted, respectively in bearings 15 provided in opposite walls of the furnace, and the extension 1 1- of one of these grate bars is provided. nf'ith a loose sprocket 16 and a clutch member 1T for locking the sprocket to the extension for rotation therewith, while the extension 13 of each grate bar is provided with a gear 18 meshingwith the ygear of the next adjacent grate bar whereby all the grate bars are rotated when power is applied to rotate l i one of them.

Loose on the extension 13 of one of the grate bars is a worm wheel 19 driven by a worm 2O receiving its power from any 1desired source, and like the sprocket 16 the worm wheel 19 has associated therewith a clutch member 21 for locking the wheel'to the extension 13 so as to rotate therewith.

Arranged above the furnace, with its lower open end in line with the opening 22, and rotatably supported within this housing is an open sided hollow fuel feed member 23, a shaft 2e from which extends laterally and i-s provided with a fixed sprocket 25 connected by a chain 26 with the sprocket 16, whereby rotation of the sprocket 16 will result in rotation of the fuel feed member.

The fuel is fed through the upper end of the housing 22 and when the grate bars are rotated by the worm 2O and worm wheel 19, power will be transmitted to the shaft 211, when the clutch member 17 is in position to lock the sprocket to the extension 111, to thereby rotate the fuel feed member 23.

As this latter member is rotated its open side wall alternately alines with the upper end of the housing and with the opening 12 and upon each full rotation will become filled and discharge .its contents upon the grate bars. If the clutch member 1T be thrown out of clutching relation with the sprocket 1G, the grate bars will rotate, but operation of the fuel feed member will cease, and likewise if the clutch-member 21 be thrown out of clutching relation with the worm wheel 19, rotation of the worm will merely turn the worm wheel 19 freely upon the extension 13 with the result that neither the grate bars nor the fuel feed member will be operated. Thus it will be seen that when the fuel feed member is in operation fuel will be fed intermittently at evenlyspaced intervals over the grate bars and that since the grate bars themselves rotate, they will be cleaned of the burnt remains of the fuel delivered to them.

In Figure 3, we have illustrated an arrangement in which both the grate control clutch lmember and the fuel feed clutch l-lO member may be varranged 'upon the same extension 13 or 14 which carries the Worm and Worm Wheel for transmitting power to the mechanism. In this instance the Worm Wheel i9 is loose on the extension and has keyed thereon a eluteh member 30 adapted to be moved into or out of looking),` engage nient with a sprocket 16 fixed to the extension7 and similarly the extension has keyed thereon a Clutch member 21 adapted to .be 'moved into or out of clutching engagement with the Worm Wheel 19.

l. In a generator, the combination of a rotatable grate bar7 a rotatable fuel feed member, a sprocket loose on the grate bar,

a connection between said sprocket and said fuel feed member, a eluteh member operable to look said sprocket to the grate bar, and means for rotating the grate bar.

2. ln a generator, the combination of a rotatable grate bar, a rotatable fuel feed member, a connection between the grate bar and said fuel feed member, a drive Wheel yloose on the zgrate bar, a clutch operable to look the Worin Wheel to the grate bar7 and means for rotating` said drive Wheel.

In testimonyr that We claim the foregoing` We have hereunto set our hands at Mik Waukee, in the eountf,7 of Milwaukee and State of Wiseonsin.
